Understanding check results
How to read a check result and what the common failure states mean.
Every time a monitor runs it records a result. Reading those results well is what turns monitoring into early warning.
Up, down, and degraded
A check is up when it meets every condition you set, down when it fails a hard condition such as an unreachable host or an error status, and degraded when it responds but slower than your budget.
Why context matters
A single failed check can be a network blip. A run of failures is an incident. Look at the surrounding results before reacting.
